Ichi chigadzirwa chakashongedzwa maviri hydraulic silinda, imwe neimwe inoshanda yakakosha uye yakasarudzika basa. Silinda imwe yakasungirirwa zvakachengeteka pasi peruoko rwekuchera. Iyo haingopei rubatsiro rwakakosha chete asiwo inoshanda senge lever, ichigonesa iyo mechaniki mukana panguva yekushanda.

Yechipiri cylinder inonamirwa kunheyo yemudzi wekubvisa. Simba reHydraulic rinofambisa iyi silinda kuti iwedzere uye kudzoreredza. Ichi chiito chakanyatsogadzirirwa kuputsa midzi yemiti, zvinobudirira kuderedza kushorwa kunowanikwa panguva yekuparadzanisa uye kubvisa midzi yemiti, nokudaro kugadzirisa midzi - kubvisa kushanda.

Tichifunga kuti chigadzirwa ichi chinoshandisa iyo yakafanana hydraulic system se hydraulic sando, silinda yakaiswa pasi peruoko ine chinodiwa chakasiyana. Inofanirwa kutora mafuta e hydraulic kubva kune silinda yeruoko. Nekuita izvi, inogona kuwiriranisa kuwedzera kwayo uye kudzoreredza neiyo yebucket cylinder. Uku kuwiriranisa kwakakosha pakuwana yakakwirira - kunyatsoshanda uye yakakwirira-yekumhanyisa kuita, zvichiita kuti michina iite midzi - mabasa ekubvisa ane yakanyanya kubereka.
